Hey guys, i picked up a scrolling LED display from a store that's going out of business. It came with a little utility that lets you set several pre-loaded messages for the sign to display, but i was hoping i could drive it with an arduino to display time, weather, etc. Just wondering if anyone has worked with one of these before, or knows where i can find a datasheet?

Hi.
This part of the PCB shows it's heart.
It has the SD card slot, it has a Winbond 25q16bv flash memory, but above all it has it's own NXP LPC1114F controller.
The controller is a 'bit' more powerful than your Arduino Uno or MEGA and has , no doubt, some proprietary code in it.
It'll be hard to find some datasheet about how to control your display other than with the tools that go with it.
I'm guessing that the controller clocks out the data to those chips that go along the edge of the PCB.
Those chips will control the separate LEDs.
I can't see what type these chips are, but that's likely the way this works.
If so, it'll have some similarities to Parola.
So check to see what these chips are, and find out if you can go that way.
16*80 dots = 1280 dots.
You'd need a bit of memory to handle that.
